When researching with rare books, it is important to remember that rare books contain so much more information than just the words found on the page!

In the General Collections, the focus of a book is usually the text and the information contained therein. While this continues to be an important aspect of researching with a rare book, in Special Collections researchers can also glean additional, important information from the physical structure of the book. How was the book constructed? Does it the book contain its original binding? Does the book have a later historical binding? These questions (and others!) can reveal additional areas of inquiry and research.

When discussing historical bindings, the Rare Books stacks of the Special Collections Research Center are filled with examples of book bindings from different periods of history. Highlighted here are two of my favorite bindings in the Special Collections Research Center stacks.

Limp vellum binding on the 1627 edition of Euclid’s Elements, QA3 .S8708 1627

With beautiful mathematical diagrams, the inside of this 1627 edition of Euclid’s Elementorum is stunning. But the binding can tell the researcher much about its user, too! It is a small, hand held volume, with a limp vellum binding. Limp vellum bindings are a  flexible vellum (calfskin) covering. These bindings were the inexpensive bookbinding choice of the day, the equivalent of the paperback.

  • Henry Baker, Employment for the Microscope: In Two Parts, QH271 .B32 1764
Baker, Emloyment of the Microscope, spine and cover

In 1764, the second edition of Employment for the Microscope was published. Filled with pasted in inserts of scientific equipment and many fold out diagrams, this book is fascinating for many reasons.

This binding is a three quarter binding, so called because the proportion or spine/corner material to side materials is 3:1. In three quarters binding, the large spine and corner areas are covered in one material (in this case, leather), while the rest of the cover is covered with either cloth or paper (in this case, cloth).

But what makes this book standout is its marbled foreedge.

Marbling is a water surface design and its swirling patterns are produced by floating color on the surface of water, which is then carefully transferred to either paper or cloth.

In this case, the marbled foreedge is in beautiful blues.
